More than 2000 Vodafone staff have been offered voluntary redundancy, but the company doesn't expect enough of them to take it to make the company an attractive investment.
"Voluntary redundancy gives employees the option to elect to leave the business for personal reasons, and to receive redundancy compensation," spokesperson Kathy Gieck told Newshub.
The offer doesn't extend to the company's frontline staff.
"Around 600 front line call centre and retail staff were exempted from this offer to avoid any disruption to customer service while we work through our company-wide review of our operating model," said Ms Gieck.
Last year it was reported the company was seeking to cut around 400 roles - a rumour the company denied.

Vodafone is expected to partially float on the NZX in the near future.
"Without question there are going to be [compulsory] redundancies," chief executive Jason Paris told Stuff. "We are not going to get where we need to get to just through a voluntary redundancy process."
The company currently employs around 2700 people.
Mr Paris said he wanted to confirm the company's plans by the end of March.
Last year, Vodafone trialled a 'digital human' in its retail stores.
